It takes time for new cells to replace damaged cells. This is a biological treatment, and you need to allow time for nature to do its work. It is like planting a seed: you must wait for the plant to grow the first leaves, and it can take months or years for that plant to produce flowers or fruit. The results of your treatment vary from one patient to another, depending on your individual condition. However, patients report noticing some changes within a few weeks. The more time that the cells have to repair and regenerate into healthy new cells, the more noticeable your improvement may become.
